Silly dogs! They hate their heartworm meds. And Freddie is VERY talented at refusing to swallow and hacking it back up as soon as you turn loose. After I crammed it down past his tonsils for the 5th time tonight, I held onto his muzzle, pointing it straight up and told him "I'm not letting go til you swallow, dammit!" He rolled an eye at me, realized I meant it, and swallowed the darned pill. Sebastian is easier IF you can get his jaws apart - he's a lot stronger than Freddie - and he too has been drugged.
